How many programmer-hours are required to have a separate page that translates between URI schemes?
Your comment, to me, implies that the 404 links' content still exists but is not at a canonical URI anymore. I'm assuming converting stuff like /2018/08/foo.html to /newscheme/fetch?foo or whatever isn't that difficult? This whole thing is one of the reasons i haven't ever set up a blog or even a website that has dynamic content, because i can't be assed to decide on a URI scheme that will "just work" with any future engine.
Someone has to have written converters, right? I know you can import some blogs to wordpress (and vice versa, export WP to other engines...)
